Corning Pyrex Rod & Tubing 120 mm OD x 3 mm Wall x 1500mm L

Mfr #: 244330     | Manufacturer: Corning

Code 7740 PYREX® borosilicate glass, the most widely known of Corning’s family of low expansion Type 1, Class A borosilicate glasses (ASTM E438 Standard Specification for Glasses in Laboratory Apparatus). It comes closest to being the ideal glass for most laboratory applications. It will withstand nearly all temperatures used in normal laboratory use. It is highly resistant to chemical attack. Its low coefficient of expansion allows it to be manufactured with relatively heavy walls giving it mechanical strength, while retaining reasonable heat resistance.
